Adonia Fathom dry dock

On May 2nd 2016, Carnival Cruises’ Adonia sailed into the history books when she became the first cruise vessel since the 1950s to sail direct from the USA to Cuba. As part of her recent overhaul, Atlantic Pacific Marine was tasked with multiple works during her dry dock in Freeport.

Our main project was the new installation of a new Alfa Laval Ballast Water Treatment system. This involved cutting out steel shelving in the engine room, and re-locating and installing steel foundations for the plant. Also we installed the AOT reactor, filter, CIP unit, lamp drive cabinet, lamp drive skid, booster pumps and all electrical panels and equipment.

Additionally, we undertook a number of steel work projects and pipe repairs throughout the vessel, plus re-positioned the emergency air generators on deck 10.

Pipework for the Ballast Water Treatment system included Cunifer, GRE, GF, and stainless steel, and encompassed all the water, sea cooling, fresh water and air supplies for the plant.

All the associated valves were supplied and installed by our team, along with all the associated electrical work.

The project was completed in 10 days, on-time and on-budget.

MBR upgrade for The World

The World is the largest privately owned residential yacht. The residents live on board as the ship travels, staying in ports for several days at a time. She has 165 luxury residences (106 apartments, 19 studio apartments, and 40 studios), all owned by the ship’s residents. Average occupancy is 150 – 200 residents and guests.

The World flies the flag of The Bahamas and has a gross tonnage of 43,524 tons. The super yacht is 644 feet long, 98 feet wide, has 12 decks and a maximum speed of 18.5 knots.

On 20th April 2016 a 6-man team from Atlantic Pacific Marine boarded The World a week before her scheduled dry dock, to cut out the existing sewage plant. The team then reinforced the steel base ready to sit the new plant on. During dry dock we installed all modulars around the tank, plus fully built and welded the 316L stainless steel main process tank itself. All connecting pipework was SCH10 stainless steel.

The new MBR system which we installed uses biological degradation and membrane separation to treat black and grey water. The process produces the highest quality discharge without requiring any addition, or generation of, chemicals which are hazardous to the environment or ship operation. The new system exceeds USCG and Alaska discharge standards.

The project was completed on-budget and on-time, taking 23 days in total from start to finish.
