As the Covid-19 crisis is still developing and the future is uncertain in the UK, we are sending our good wishes to you, your family, friends and colleagues.

We are all having to evolve the way in which we conduct our business. Whilst Calvey Marine prefer to build and maintain relationships with our Clients face-to-face, thankfully due to connectivity and modern technology, we will be able to keep our Clients such as yourself updated with relevant and informative information regarding our Principals’ services, in the hope that we can support with any current or future requirements you have. I hope this will be well received, but if you not feel that this is relevant or do not wish to receive such information please do let me know.

After discussing lack of dockspace and difficulties drydocking ships due to global restrictions at yards that do have availability, our Principals at SeaTec informed me of a recent topical case study that I thought could be of interest.


SeaTec embarked on a Turnkey installation project for a Ballast Water Treatment System on board a 30,000DWT Bulk Carrier, while sailing. The vessel was trading in remote regions, with only one stop in Singapore, and all arrangements had to be done during the Christmas and New Year period.


In addition to challenge with the vessel being small bulker accommodating maximum 6 berths and on a tight schedule, there was only one chance to load all the materials and crew on board. SeaTec Subsea was later involved during a stop in Singapore for some shell valves to be blinded underwater

The project has three stages:

  1. Engineering stage consists of 3D Scanning the vessel, and preparing the piping installation plan and isometric drawings for Pipes prefabrication
  2. Procurement & Logistics stage is the Procurement of Electrical Material, Pipe fabrication, procurement and prefabrication of equipment foundations
  3. Installation on board which requires a SeaTec Riding Squad Team (Mechanicals, Fitters, Welders) sailed with the vessel for about Two months under the supervision and guidance of SeaTec Project Manager.


Despite the challenges, the close cooperation of between the Seatec Projects & New builds Department, Riding Squads, and the Subsea department resulted in the successful completion of the project.

Key Achievements

  • Completing the retrofit with just 7 technicians, without any incidents or delay, and without stopping the vessel.
  • ~ $460k revenue for the owners having maintained the vessel in the market, avoiding DD
