Osbit boat landing system for Hornsea
Osbit Ltd, the offshore engineering and technology company, has been awarded a project to deliver an innovative boat landing and access system. This innovative system will be fitted to a Gulf Marine Services jack-up accommodation vessel which is destined for operations on Dong Energy’s Hornsea Project One Wind Farm.
The accommodation vessel is self-elevating and self-propelled and capable of being dynamically positioned and will be positioned close to installation sites.
The new system will be designed to facilitate the safe transfer of crew members and technicians from the jacked-up accommodation vessel to crew transfer vessels that will take them to the work site. Osbit claims that its original thinking has resulted in a highly practical boat landing system that is an industry first. Utilising a unique access tower with an integrated crew transfer vessel boat landing, technicians will be able to safely access transfer vessels regardless of whether the GMS accommodation vessel is in a floating position or has been jacked-up to a pre-determined deck height of 21 metres above sea level.
Osbit’s system is an integral part of the operation which will allow work crews to remain offshore, rather than make daily trips to and from shore and will facilitate up to 50 crew transfers each day. The vessel, and its sister accommodation vessel, will be deployed 120 kilometres off the Yorkshire coast. The boat landing system will be raised and lowered into position using the vessel’s onboard crane, and will feature a waiting area and vessel interface that mirrors the buffer and ladder units found on traditional turbine transition pieces. The system will be installed when the vessel arrives in the North East at the start of 2018.
Brendon Hayward, Managing Director of Osbit Ltd, said, “In delivering our first project for GMS UK Ltd we are proud to be involved in the development of the world’s largest offshore wind farm. This boat landing system will enable safe and efficient crew transfer, with minimal operational interference. The versatility of the system will ensure that transfers can take place without being affected by the jack-up vessel’s height and therefore it won’t interfere with operations or substation access. As a result, the vessel can become a hub for technicians working on the substations or turbines, delivering more efficient and cost-effective use of the project’s offshore accommodation provision, while maintaining safety at all times.”
Duncan Anderson, Chief Executive Officer of Gulf Marine Services, said, “As a business, we have constantly been evaluating and developing more efficient means of deploying equipment and services in shallow water. In the oil and gas industry we have led the field in light cantilever intervention development and this boat landing system we are producing in tandem with Osbit is another first of its kind in the world.”
