Experience, competence and a wide range of propulsion and manoeuvring make up an extensive range of customized configurations for the specific vessel.
Brunvoll has extensive knowledge from experience through deliveries to more than 50 Shuttle Tankers the last two decades as well as through deliveries of propulsion and manoueuvring systems to hundreds of advanced offshore vessels of different types. Our extensive in-house R&D resources are dedicated to continuous refinement of the concepts offered to ensure deliveries that live up to the highest standards of reliability, efficiency and sustainability. This while maintaining a close dialogue with ship owners being the end users of the equipment and our Service department.
Experience, competence and a wide range of propulsion and manoeuvring make up an extensive range of customized configurations for the specific vessel. Propeller systems for 2-stroke and 4-stroke engines, as well as the entire thruster package from one supplier, is easy for the shipyard during building and for the shipowner during operation. Smooth operation of the shuttle tanker and optimum uptime is the target for all parties - supplier included.
Clients' repeating confidence in our abilities and performance gained by their prior experience, have resulted in Brunvoll being entrusted with the task of delivering repeat orders of propulsion and manoeuvring systems to new Shuttle tanker concepts.
A hybrid propulsion system based on diesel/gas electric and batteries offers shuttle tankers the perfect system to meet the wide variety in operation modes, and often in harsh offshore sea conditions. Operation flexibility from an efficient propulsion system, unmatched manoeuvring capabilities, and high redundancy are essential to ensure safe operation of the vessel.
A fully diesel-electric propulsion system can be powered by generator sets, driven by diesel or dual-fuel engines, or from the installed battery package. The batteries ensure a dynamic system with possibilities for electric running mode powered by batteries, for peak shaving, and in general increased system redundancy. A diesel-electric-battery hybrid system can also lower the running hours of the power machinery and reduce maintenance cost.
A CPP 2-stroke diesel mechanical system is a reliable, robust and maintenance friendly configuration with high fuel efficiency. The smooth operation and flexibility with the CP-propeller and the complete configuration of thrusters offer unmatched manoeuvring capabilities and safe operation of the vessel.
All systems are customized for the particular vessel. Stringent safety regulations and environmental concerns are in focus when designing a system for any type of ship to ensure cost efficiency and reliability.
During Sea Trials/Gas Trials this we tested the battery installation onboard our E-shuttle Altera Wave. The vessel is built to DNVGL’s Battery Power notation and has a battery pack of 1808kWh installed.
The test was a great success and showed that the vessel was able to maintain 6-7 knots for almost 20 minutes on batteries only! The main purpose of the batteries is to reduce fuel consumption and emissions by peak shaving, prevent black-outs, and improve safety during DP operations by replacing power from one generator if needed.
