Welcome to the Motor-Boat Maintenance Section (Commercial & Leisure), here you will find information on the maintenance programme, the membership process, and how to access the maintenance database.

The Maintenance Programme

It is a globally accessible Maintenance Programme designed to suit the needs of owners, skippers, and those responsible for the maintenance and operation of charter fleets.

Our programme covers the mechanical, electrical, domestic, fire and safety systems. Staff at head office and local managers can remotely access the database to observe the progress of maintenance required for their vessels. Leisure boat owners can sit comfortably at home, planning their maintenance periods.

 

Maintenance Plans

Primary Plan covers all the mechanics of a boat from the fuel tank to the propeller and takes priority over all other plans.

Primary Drive Plan is the drive system for a boat, both these primary plans include the critical spare parts list.

Secondary Plan covers the auxiliary, domestic, and ancillary systems.

 

Maintenance Tasks

The tasks are adapted to a vessel’s operational requirements. Whilst a fleet manager will engage their shore-based maintenance staff, small commercial operators and leisure boaters are encouraged through our maintenance programme to manage a variety of tasks themselves, and only occasionally look to the boatyard for assistance, thus giving them a better understanding of the systems on their boat.

 

Maintenance Schedules

Maintenance Scheduling is a way to help the planning of maintenance. Yearly monthly, weekly, daily, and even hourly checks form part of the maintenance schedule. Flexible scheduling has been designed which can be readily adapted to a cruising programme, and periods alongside. We find that leisure boat owners will set their maintenance at the beginning or end of the cruising season, whereas commercial operators with much higher running times tend to base their maintenances on an hourly frequency.

 

Safety & Fire Equipment Maintenance

Basic safety & fire maintenance practices are essential for the well-being and safety of your boat and crew.

In many countries the authorities are now looking for paperwork showing test certificates and expiry dates for fire and safety equipment, VHF and AIS certification, plus LPG testing. These are systems covered by imardex-marine’s Maintenance Programme.

 

Commercial & Leisure Boat Operators - Additional Plans

If you are a Commercial Operator and require maintenance plans that are not illustrated on our database, such as, diving compressors and decompression chambers, dredging equipment, lifts, surveying equipment, specialist medical and research equipment etc, then please contact us below for further details.

The Membership Package

Please click through to ‘Membership Desk’ to check whether your vessel, engine and drive system are included.

Membership is required to access imardex-marine’s maintenance database. To become a member simply click ‘Membership Desk’ and select to pay monthly or annually where you will benefit from a discounted fee.

 

 

Benefits of Membership

At imardex-marine we expect that the membership and the use of its maintenance programmes will bring the following benefits:

  • Greater understanding and knowledge of the systems on your boat
  • A safer boating experience for crew and passengers
  • Increased operational efficiency and fewer breakdowns when underway
  • Reduction in the general running costs
  • Longer life expectancy of machinery

 

Marine Insurance

Marine underwriters require that your insured boat be well maintained and seaworthy. We provide knowledge and understanding of how to manage your maintenance in such a way that it demonstrates that you have taken maintenance seriously.

 

Services included in the Membership Package

Pre-Departure Checks - A special checklist identifies the necessary safeguards to be undertaken prior to departure. It is supplemented by a list of checks and helpful hints to be followed when underway.

Winterising - A guide and checklist available for winterising your Main Propulsion, Auxiliary and Domestic Systems.

Boatyard Work Guide and Check List - A comprehensive useful guide and checklist, prior to a boat yard starting work on your boat. This information has been put together with the help of the imardex-marine team and members who have many years of experience in dealing with boatyards and marine workshops.

Action after Grounding - A checklist to assist the boater through a grounding scenario, and what to look for when inspecting keels, rudders and hull section, after such an event.

The Modern Diesel Engine its Fuel and the Environment

Modern Diesel Engines

To reduce the increasing threat to the environment and global warming, the harmful emissions of diesel engines have to be reduced. The search for cleaner emissions has resulted in engine manufacturers redesigning fuel delivery systems to the cylinder. Common rail diesel delivery being one system. Injector pressures in the 70’s was around 300 bar (4,351 psi), today pressures are in excess of 2,500 bar (29,000 psi), this higher injection pressure is a key factor in reducing an engine’s untreated emissions. It also improves atomisation by having a better fuel air mixture ratio, meaning that optimum combustion is achieved giving enhanced power output and efficiency.

Diesel Fuel & Additives

To reduce harmful emissions from diesel engines, the sulphur content of diesel fuel over the last few years has been reduced from 500 parts per million to 15 ppm. This fuel is now known as ULSD (ultra-low sulphur diesel). This dramatic reduction has resulted in problems for manufactures and operators of diesel engines and diesel fuel distributors. There is a full programme of maintenance and preventative measures to combat diesel bug outlined in the members section, Engine and Generator Lubricating Oils can be sent for testing, we can advise you on this.

Engine Maintenance

We have designed a comprehensive maintenance programme to be followed by owners of marine diesel engines. Requiring only basic skills, this maintenance programme covers all the mechanical work to keep the engine in a seaworthy condition. It does not include tasks where rebuilding is required.

Modern Engines & Drive Systems

Modern engines have a higher power to weight ratio and are usually more reliable and cleaner than older engines. Many now have electronic controls to optimize fuel consumption and efficiency. Our maintenance plans reflect this increase in power, by the addition of rescheduled maintenance tasks.
