Jee Completes Power Cable Analysis for Offshore Wind
Jee Ltd. (Tonbridge, England) has completed a Centrica Renewable Energy Ltd. (Windsor, England) contract for a subsea power cable analysis that could reduce future operation and maintenance costs on an offshore wind project.

Centrica Renewable Energy commissioned Jee to identify scenarios that could lead to premature failure of the subsea power cables on the Lynn and Inner Dowsing offshore wind project given different environmental conditions and amounts of seabed scour around the base of the wind turbine foundations.

Using OrcaFlex software, a powerful analysis tool for subsea risers, pipelines, umbilicals and cables, Jee modeled the cables to assess loads and movements that could potentially cause premature failure. Centrica will use this information to decide if any cables are required to be made safe with remedial works, therefore mitigating the risk of a future failure and avoiding the costs associated with loss of energy production and cable replacement.

The Lynn and Inner Dowsing project comprises two adjacent wind farms 5 kilometers off the Lincolnshire coast. Together, they have an installed capacity of 194 megawatts, enough power to meet the annual demand of more than 130,000 homes.


Bibby Gets Two Quantum Work-Class ROVs
Bibby Offshore (Aberdeen, Scotland) has taken delivery of two Quantum MkIII 250-horsepower, 3,000-meter-rated work-class ROVs, increasing their ROV fleet to nine SMD (Newcastle upon Tyne, England) vehicles, including one Atom and six Quasars. Each of the high-specification Quantum work-class ROV systems includes SMD’s Extended Tophat Tether Management System (TMS), telescopic A-Frame, umbilical winch, deck pack and fully integrated control cabin.

The Quantum is the largest vehicle within SMD’s Q-Series work-class ROV range, with a 350-kilogram payload, 1,400 kilograms of horizontal thrust capability and 210 LPM tooling supply. It utilizes the latest multiplatform SMD Curvetech components and DVECS-S advanced dynamic positioning system.


Final Testing to Start on World’s First Subsea Wet Gas Compressor
The world’s first subsea wet gas compressor station is now ready for final testing at Horsøy outside Bergen, Norway, before being prepared for installation and hook-up to Gullfaks C in 201, Statoil (Stavanger, Norway) announced.

By adding 22 million extra barrels of oil equivalent from the Gullfaks South Brent reservoir the compressor will help extend the field’s productive life.

The compressor is developed in cooperation with OneSubsea (Houston, Texas). The delivery from OneSubsea consists of a 420-tonne protective structure, a compressor station with two compressors totaling 650 tonnes, and all necessary topsides equipment for power supply and control of the plant.

The last test phase will verify that all units work as expected.

Compression on the seabed gives a better effect than a conventional topside compressor. In addition, there is an advantage that the platform avoids the increase in weight and space a topside compression module requires. The advantage of a wet gas compression facility is that it does not require any treatment of the wellstream before compression. This makes for smaller modules and a simpler construction on the seabed.


KR, APEC to Promote LNG-Fueled Ships in Region
The Korean Register (KR) will work alongside the Asia-Pacific Economic Cooperation Secretariat (APEC) to promote the use of LNG-fueled ships in the APEC region. Work will also include a program to share knowledge and best practices across the APEC region with the aim of promoting this new technology. APEC wants to work towards an energy-efficient, sustainable, low-carbon transport future. LNG-fueled shipping is believed to be one of the optimum potential solutions to help achieve this aim. KR is to be supported by Japanese and Canadian representatives within APEC’s Maritime Expert Group and Transport Working Group. The class society will undertake an extensive program of research focusing on the current application of LNG technologies, associated safety aspects, seaborne trade statistics and best practices. Results will be shared with APEC member economies to help narrow the technology gap between countries.

The project gets underway shortly and is expected to be completed by the end of 2015.


Cranston Eagle Hooks for US Coast Guard Cutters
Delta “T” Systems (Riviera Beach, Florida) supplied Cranston Eagle hooks to crane manufacturer Appleton Marine, Inc. (Appleton, Wisconsin) to be used on medium endurance cutters and national security cutters to move small boats into the water from bigger ships and to load cargo.

The hook models supplied include the 3.5-ton-rated APR-356-CBH and the 4.5-ton-rated 20-APR-456-CBH.


BMT Oceanica to Conduct Oil Spill Study
BMT Oceanica (Perth, Australia) has been awarded the Australian Petroleum Production & Exploration Association’s (APPEA) “Understanding the Risks of Unplanned Discharges” study. BMT Oceanica will be working with Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) to deliver this project to update current knowledge on the potential environmental impacts of unplanned releases of hydrocarbons and other chemicals into the marine environment. Phase one of the project is already underway and includes an international scientific review and the development of a vulnerability assessment model that will help APPEA members enhance environmental and oil spill response plans. This will be achieved by aligning risk assessment to the vulnerability of key environmental receptors. This work complements BMT Oceanica’s other current energy consultancy engagements with major operators in western Australia.
