Optimisation of your system reduces energy consumption, you achieve reduced emissions and gain reduced operational cost
Depending on the age and condition of the equipment, an upgrade or retrofit is an affordable way to extend the life of your system and potentially boost performance for greater productivity.
When a system is well serviced, its life can easily be extended for the lifetime of the vessel.
Whether you’re looking for an upgrade to meet different running conditions or implement a more comprehensive retrofit, our engineers can help you identify the best options to optimise your vessel.
During the lifetime of a vessel the operation profile may be changed. New tasks and purposes, change of ownership, or new technology with changes in class requirements may cause need for an upgrade/retrofit in order to optimise the vessel's efficiency.
There are several ways to achieve increased efficiency. Our experienced engineering teams may assist you in finding the best solution;

Austral Fisheries, Western Australia
This is a great story with a project that involved Austral Fisheries & Brunvoll in looking at reducing Fuel Consumption & Carbon offset costs on the fishing Vessel Atlas Cove (ex Osterbris out of Bergen Norway).
The work program involved changing to a bespoke Brunvoll Multi Step Gearbox along with a reduction in the Main Engine Horsepower & Variable Frequency PTO off the stern of the Gearbox with an expectation of fuel savings between 19 – 22%.
There was quite a considerable amount of work required but she sailed on time and without incident for a 100-day trip to the remote sub-Antarctic waters of Heard Island.
It took about 6 months for the captains to come to understand and really extract the full value of the new drive train to achieve what ended up being operational and fuel efficiency gains that could only be described as ‘amazing’.
In 2019, the Atlas Cove achieved a 37% fuel saving compared to its pre-refit consumption figures.
This compares very closely with 2018 (38%).
In real numbers this is 1,185,887 L of fuel, and 3666t CO2-e emissions saved in 2019.
At 85c/L for fuel, this is a $1,008,000 saving.
As well asa ~$44,000 saving worth of carbon offsets.
Some good news from 2020, with a slightly different mix of fishing, the Atlas Cove saved a whopping 45% on fuel usage compared to its pre-refit consumption. This equates to 994,000 L fuel saved, and 3069t CO2-e emissions.
At 78c/L this is a $775,000 saving, plus an additional $32,000 worth of carbon offset savings.
Note that this investment has paid for itself in less than 3 yrs.
This gearbox is the gift that keeps on giving!
It's a fact that electrical parts and the system's software evolve quickly, and become obsolete after several years of good operation.
Upgrade to new technology increases safety, efficiency and durability.
An upgrade may consist of a new control system, new functionality with DP, Joystick and autocrossing.
