The Challenge
The main challenge of the scope was the short schedule and late notice, with no prior preparation completed. Any delay in the cable pull-in would have caused a significant setback to the overall project schedule and delay the completion day.
Many interfaces also needed comprehensive technical management, to align and deliver a slick and safe operation whilst maintaining asset integrity. Industry standards (DNV) were also applied to the engineering to satisfy the Marine Warranty and ensure the additional level of surety in the operations.
Additionally, the site presented a number of environmental challenges, including shallow water (<2m), shifting sand banks and longshore currents. Pragmatic and bullet-proof engineering was required to make the project a success and deliver to the high required standards.
The Solution
Tadek supplied lead project engineering to the landfall project, developing all procedures, storyboards, risk assessment for the pull-in, burial and trenching operations. Working directly with the numerous suppliers to ensure technical alignment of a fleet of RHIBs, multicat, Cable Lay Vessel, several winches, fleet of excavators and other equipment.
The Project’s high QHSE standards were also met through Tadek engineering, delivered through detailed HIRAs, ROC Drills, HSE plans and Inspection plans.
On site Project Engineering was also a core part of Tadek’s delivery, overseeing the technical aspects of the operations and keeping the flow of the pull-in going with on-hand MOCs, DPRs and as-built reporting. The Project Engineers were a core part of the delivery team, with excellent and invaluable interfaces to the operational team, clients and Marine Warranty, ensuring the delivery of the operations were efficient and safe.
The Outcome
A comprehensive suite of procedures with accompanying storyboards were produced within the express schedule, with particular value in the clarity and ‘usefulness’ of the deliverables. This was achieved through close collaboration with the operational crew, featuring clear drawings showing each step with relevant detail to achieve the objectives.
The on-site engineers ensured the pull-in and burial was achieved to schedule, with exceptional focus on safety to deliver a safe and slick operation. Aditonaly, reporting and recordi0ng was undertaken throughout to enable delivery of a comprehensive as-built package to be delivered to close out the engineering support for the project.
The central role achieved by the Tadek lead engineer ensured harmony between the many different interfaces and suppliers, including survey, plant, winches, vessels, metocean and more, ultimately enabling the successful delivery of the scope.
“The key to the successful cable landing operation was the good planning and preparation of the activity sequence and the efficient communication and coordination between Prysmian’s vessel and Subcontractor onshore personnel managing the overall operation both offshore and onshore”
