Projects we're proud of


The Kirinskoye GCF included a 20-inch pipeline, 10 inch pipelines, 2 types of umbilicals, Manifold, 2 types of PLET, SDU, 7 wells (x-mas trees).

Seafasten was responsible for all of the engineering of the sea-fastenings and the structural design of a number of installation aids using the MCS Everest.


All sea-fastening design of multiple rigid spools and their spreader beams, transported on barges to the field and installed using the MV Pride.

The largest spool being 20inch in diameter and approximately 100m long.

Number of installation challenges such as head crane head room and load out height from deck.


The Ichthys Venturer FPSO is a 336m long FPSO designed to process and store the condensate delivered from the Ichthys LNG project’s central processing facility, Ichthys Explorer, before periodically offloading it to carriers.

Seafasten provides ongoing structural engineering support to ensure existing facilities, modifications, and upgrades comply with international design standards.

Unique Weldless Sea-Fastening Solution


About us

We used Seafasten to completely manage all of our seafastening needs for a medium sized project. They looked after the design, drawings fabrication and logistics, and we will definitely be using them again.


Imam Mehedee


Have used Seafasten a few times whilst in Perth. A fantastic company with great customer service. I feel like we dont have to worry about that aspect of our business anymore.


Roudro Rony


I outsourced multiple seafastening design and checking jobs to Seafasten Offshore whilst working for an offshore installation company. I received a very efficient service, quick turn around and a high quality of design.


Charlotte Dowling

Structural TA

Carrick is always willing to do the little extra tasks that make a difference and a pleasure to do business. I have referred a number of businesses to Seafasten and their feedback to me is they are happy with their service and support.


Matt Brandon


Seafasten has a wonderful work ethic and has a good leader (Carrick) at the helm. I would definitely work with them in the future
