Lisnave – What is Dry-docking and why do we do it?

From Lisnave we share a work  that unveils a little of what we’ve been working on for the past 15 months.

The process of dry-docking  at Lisnave Estaleiros Navais refers to when a vessel is taken to the service yard and brought to dry land so that submerged portions of the hull can be cleaned and inspected. This work is both preventative as well as a regulatory requirement within the industry. When second-hand purchased vessels are due for dry-docking, they are rebranded and assessed to meet all Teekay standards.

At Teekay, vessels are scheduled for dry-docking once every five years, with intermediate surveys taking place in between. Once the vessels are put back into service, they are more eco-friendly and fuel-efficient. At its core, the process of dry-docking is about our commitment to Operational Leadership and our pledge to operate the best ships in the industry.

If the world of dry-docking had one moto, it would be “plan, plan, plan and plan some more.”

In 2015, the Teekay Tankers team completed the largest dry-docking program to date, successfully processing 17 vessels over the course of 382 days of service time. The process itself requires careful planning and preparation. Every minute detail needs to be taken into consideration when undertaking a major project such as the dry-docking of a vessel – and even more so when trying to coordinate 17 of them in a year.

So what does the actual dry-docking process entail? Let’s have a look of this vídeo filmed at Lisnave , Portugal .

Some history about Lisnave shipping yards

Lisnave’s origin dates back to January 1, 1937, when the CUF Group took over the concession of the Rocha Shiprepair Yard concession situated on the north bank of the Tagus estuary in Lisbon.

Later in September 1961 the company adopted the name Lisnave – Estaleiros Navais de Lisboa and the company expanded on the South bank of the Tagus where the new Margueira yard was built, with facilities to accommodate the largest vessels being built.

In 1973 Setenave Estaleiros Navais de Setúbal was created and a new shipbuilding and shiprepair Yard was built at Mitrena in Setúbal to cope with increased demand, both for ship repairing and shipbuilding.

Resulting from the needed rationalisation of the European shiprepair industry, in mid-1997 a restructuring plan was implemented to meet the forecast shiprepair and conversion needs for the incoming 21st Century.

The restructuring plan was completed in the end of the year 2000, following the closing of the margueira Yard and the general upgrading of the existing Yard and the construction of 3 additional Panamax size Drydocks (the Hydrolift).

All activities are since then concentrated in Mitrena.
