Oil Salvage Operation Extracts 400 Tons Of Heavy Fuel Oil from Singapore Shipwreck

A Miko Marine Moskito hot tap tool and oil recovery system was used to extract 400 tons of heavy fuel oil from the tanks of the sunken cargo vessel Thorco Cloud. The wreck lies in two sections 1,730 m apart and 70 m deep in the middle of the eastbound traffic lane of the Singapore Strait.

The heavy oil in the fuel tanks and trapped compartments has been a major pollution hazard since the collision in December 2015. Bumi Subsea provided ROVs and the vessel Surf Allamanda, owned by Bourbon Offshore, which served as the work platform during the oil salvage operation.

Hybrid Drive Systems Constructed in Estonia Pave the Way for New Law Enforcement Vessels

PBES and NORIS Automation GmbH entered a partnership on the hybrid drive systems for Europe’s first battery hybrid patrol vessel. The 45-m-long vessel is under construction at Baltic Workboats Shipyard in Estonia, and it will have 273 kWh of PBES Power 65 battery modules, which offer reduced sound and heat signatures. The PBES energy storage system is designed to integrate with the NORIS electrical infrastructure on the vessel.

International Insurance Provider Thomas Miller Acquires Technical Consultancy Brookes Bell

Insurance services provider Thomas Miller acquired Brookes Bell, a technical and surveying consultancy with offices in Liverpool, London, Glasgow, Shanghai, Hong Kong and Singapore. Brookes Bell provides services in emergency response, casualty investigation, salvage and wreck removal, scientific cargo expertise, forensic engineering and expert witness services. The firm is also a leader in research and development of ship design support to enhance maritime safety and technology.

Australian Organization Partners with Saildrone to Acquire USVs for Research

The Commonwealth Scientific and Industrial Research Organisation (CSIRO Australia) formed a partnership with San Francisco-based ocean technology start-up Saildrone to bring three USVs to Australia. CSIRO will use the Saildrone USVs to measure ocean temperatures, salinity and carbon, which is critical information for understanding the role of the oceans in the climate system. The three Saildrones will provide unprecedented access to parts of the ocean, particularly the Southern Ocean, that are otherwise unstudied.

Scottish Production Optimization Company Secures Investment from EV Private Equity

Aberdeen-based Enpro Subsea secured investment from EV Private Equity to grow its production optimization business into new and existing international markets and develop its range of production optimization and intervention technologies. Enpro began 2018 with projects ongoing in the U.K. Continental Shelf, West Africa and Gulf of Mexico. EV Private Equity is providing support as part of its pledge to invest $200 million into fast-growing North Sea businesses.

Legacy Locker Program Allows Reuse Of Recovered and Recycled Subsea Equipment

Systems Engineering & Assessment Ltd. (SEA) and Spirit Energy are promoting the recycling of subsea production equipment under SEA’s Legacy Locker program. The companies are recycling two Aker third-generation subsea control modules (SCMs), following the decommissioning of Spirit Energy’s Ann field. SEA’s refurbishment of the equipment means the modules will be fully functional and available for reuse through Legacy Locker, a repository of new and refurbished equipment that is tested, refurbished, recertified or reverse-engineered by SEA’s subsea engineers.

Communication and Monitoring Systems Experts W·SENSE Join UK Marine Robotics Centre

Pioneering underwater wireless networking and communications systems developer W·SENSE Ltd. has joined the National Oceanography Centre’s (NOC) Marine Robotics Innovation Centre as a strategic partner. W·SENSE was initially established as part of the Sapienza University of Rome, specializing in monitoring and communication systems with pioneering patented solutions in the internet of underwater things (IoUT). The company has been editor of networked scenarios and of the NATO NIAG 190 on JANUS evolution, and it is currently coordinating the EC EASME ArcheoSub project.

Remotely Operated Fire-Fighting Vessels Will Offer ‘Eye-in-the-Fire’ Capabilities

Robert Allan Ltd. and Kongsberg Maritime are collaborating on the development of a remotely operated fireboat that allows first responders to attack port fires more aggressively. The RALamander fireboat offers in-close firefighting and “eye-in-the-fire” capabilities. The first in the series, the 20-m RALamander 2000, will be equipped with Fi Fi 1 capability with a total pumping capacity of 2,400 m3/hr with optional foam. A retractable mast can bring one of the three monitors to a high point of attack for shipboard or dock fires.

Chelsea Technologies Scrubber System Receives ClassNK Certification

Chelsea Technologies’ Sea Sentry washwater monitoring system for ship exhaust gas cleaning systems has been certified by ClassNK. Sea Sentry provides a fully autonomous washwater monitoring system that monitors both the water inlet and outlet of wet exhaust gas scrubber systems. Sea Sentry has the ability to accurately measure the polycyclic aromatic hydrocarbon, absorbance, turbidity (to ISO 7027: 1999), temperature and pH of scrubber washwater. It can monitor open-loop, closed-loop and hybrid scrubber systems, setting the gold standard for accurate washwater monitoring.

Two-Year Trial Proves Efficacy of I-Tech’s Organic Anti-fouling Coating

A two-year trial of a hull coating containing the bio-repellent active agent Selektope on a 46,067-dwt chemical and products carrier confirmed the ingredient’s hard fouling prevention power. Selektope is an organic, nonmetal compound that prevents barnacle fouling by temporarily activating the swimming behavior of barnacle cyprid larvae, making it impossible for them to settle on the hull. It has high efficacy at extremely low concentrations (0.1 percent w/w), is ultralow leaching, and offers paint manufacturers the flexibility to boost copper-based paint formulations or replace copper completely.

Netherlands Workshop Receives DNV GL Approval

AEGIR-Marine’s new workshop received approval from DNV GL, making it the first brand-independent service provider in the Netherlands with an approved workshop for repair and maintenance of propulsion systems.Workshop approval includes the quality of maintenance on propulsion systems, workplace routing, workplace safety, hazardous substances handling and risk management. The workshop allows AEGIR-Marine to perform spin tests, running and simulating propeller and thruster speeds in real time.

Dynamic Underwater Laser Mapping Technique Developed for ROVs

Newton Research Labs Inc. and Sonardyne International Ltd. completed tests to integrate Newton Labs’ underwater laser scanners with Sonardyne’s acoustically aided inertial navigation system for underwater vehicles, SPRINT-Mapper. Newton and Sonardyne entered into a formal collaboration in late 2017 to develop and promote dynamic underwater laser mapping, a rapidly emerging survey technique that significantly reduces the time needed to carry out inspections using underwater vehicles, including ROVs and manned submersibles. Now, an underwater vehicle fitted with a Newton underwater laser, is able to capture high-density point clouds of subsea assets and environments while on the move. The milestone paves the way for greater adoption of mobile laser mapping technology to survey seafloor sites and subsea structures.

Cornish Company Receives First Grant

Marine-i, an EU-funded program to boost the marine technology sector in Cornwall, made its first grant award to Triskel Marine, a technology company that recently moved to the Marine Enterprise Zone in Hayle, Cornwall. Enterprise Zones are designated areas across England that provide tax breaks and government support for new and expanding firms. The grant, the first from Marine-i’s Marine Challenge Fund, has enabled Triskel to build a comprehensive hybrid test rig for a new hybrid energy product, which the company expects to unveil at a launch event in the U.S. in fall 2018.

Stern Tube Seal Repair in Antwerp Uses Flexible Mobdock Instead of Drydocking

Hydrex diver and technician teams carried out an underwater stern tube seal repair on a tanker berthed in Antwerp. The ship was suffering from an oil leak, making an on-site repair necessary. Using a Hydrex flexible mobdock, the team was able to make the repair on site underwater. The operation started with a thorough underwater inspection of the stern tube seal assembly, which revealed that a rope and a fishing net were entangled around it. Both were removed by divers, and the team then removed and replaced the three damaged seals.
