Shell UK requested Survitec in May 2018 for a turnkey answer to extend lifeboat capability on the Shearwater fuel hub by greater than 22%. Survitec’s answer was to interchange the present three 49-person capability lifeboats, with three 60-person lifeboats taking the overall capability from 147 to 180.
The venture was pushed by an anticipated upturn in exercise offshore, together with a significant offshore turnaround deliberate for 2020, which made provision of further offshore bedding capability a precedence to permit the secure and environment friendly operating of the Shearwater asset. However, on condition that each the SOLAS (Safety of Life at Sea) Convention and the UK’s nationwide regulatory physique HSE (Health and Safety Executive) have strict guidelines governing security, the uplift in personnel on the hub required an elevated lifeboat capability.
Lack of crane protection and a compressed venture supply schedule have been simply two of the challenges Survitec and the venture workforce overcame, as they commissioned three new lifeboats and modified davits on the Shearwater platform throughout 2018.
Andrew Sinclair, Shell Project Manager mentioned: “This venture was a precedence for the Shearwater Asset permitting for a ramp up in venture and upkeep exercise to assist unlock the platforms potential and safe a vivid future for the ability.”
As Survitec’s 60-person lifeboats are bigger than the present boats, the present davits have been too small for the brand new stock so had to get replaced. The marine offshore security specialist had solely a two-month window wherein to ship, set up and fee the brand new gear.
Access was additionally difficult. The place of the lifeboats on the hub didn’t permit for crane entry, and scorching work on website was prohibited. Further, just one lifeboat at a time might be taken out of service, including to the logistical complexity to the venture.
Marc McEwan, Head of Projects, Survitec, mentioned: “We knew from the outset that this was a difficult venture that wanted a special method to fulfill the tight timeline. Allocating the precise assets from the beginning have been key to the venture’s success. Crane entry to the positioning was restricted, so we additionally needed to collect the proper info and element to allow the general plan to develop earlier than we put in the davits and rolled out the lifeboats within the two-month window.”
McEwan defined that Survitec’s first step was to hold out a 3D survey of the Shearwater platform so Survitec may higher perceive the format of the positioning and any entry limitations. The three lifeboats would sit in the identical location as the present boats, parallel to one another alongside one facet of the hub.
The 3D survey, nonetheless, confirmed that new longer davit upkeep platforms have been required to assist the bigger lifeboat. These new prime sections have been designed, fabricated and examined onshore by Survitec over a four-week interval, witnessed and accredited by Lloyd’s Register.
During the set up section Survitec labored in tandem with Zenith Structural who developed a bespoke lifting association to get the brand new prime sections and ancillary gear into place for ultimate set up.
McEwan mentioned: “Moving each the davit prime sections and lifeboats into their positions was one of many extra sophisticated features of the operation, however Shell UK’s workforce of technicians and the broader assist workforce have been sensible to work with and utterly understood the platform’s entry limitations and the North Sea climate.”
Survitec had entry to the rig throughout September and October final 12 months. It drew upon its lifeboat design experience, regulation perception and fulfilment data to ship the complete scope of the venture on deadline.
