Let me introduce myself, I’m Captain Francesco Aiello. I currently live in my hometown of Sorrento (NA) Italy. For over thirty years I was a harbor pilot in Gaeta, which lies to the North of Naples. On many occasions, I have seen remarkable difficulties and dangerous situations that affect marine pilots during the transfer from the pilot boat to the ship and vice versa.

This is not always executed in the safest way. Pilots are involved in numerous accidents, some of which can be fatal.

This is mainly due to failing to observe the rules dictated by the IMO on the correct use of pilot ladders. However, even when respecting all of the standards laid down by SOLAS regarding the pilot ladder, accidents occur very frequently. The ladder can get trapped between the hulls of the ship and pilot boat. This happens when the pilot boat rises in the water, pins the ladder against the ship and then pulls it down.
This eventuality is also foreseen by the IMO which prescribes that the last four steps are not made of wood but of rubber.



The entrapment problem has not yet been solved and has prompted me to seek a solution. My very simple idea (patented) has been internationally recognized as innovative.
My attention was focused on the pilot boat that has undergone a remarkable evolution over the years. Today there are pilot boats built with increasingly modern criteria and equipped with increasingly advanced equipment and instruments. But however modern and efficient the current pilot boats may be, they always risk trapping the pilot ladder and ultimately causing injuries to the pilot.


My innovation focuses on the main deck. It is designed with four protruding platforms, two on each side : two placed toward the bow and the other two placed to the rear forming a single body with the main deck. When the pilot boat is alongside the ship, the protrusions of each side create a recess in which the pilot ladder, even if dropped too low in the water, does not run the risk of being crushed or dragged. This recess has a wide space between the two protrusions where the pilot ladder is completely free when dropped, because the sides of the ship and the pilot boat are separated.

Despite the ship’s often high speed, the pilot boat can approach making sure that the pilot ladder is kept within the recess between the two protrusions until the pilot is ready to make the transfer. This also makes the job of the coxswain less stressful as they do not have to worry about entangling the pilot ladder and causing harm to their crew.

The attached images clearly highlight the recess. This innovation was the subject of a feasibility study carried out by a naval engineer and professor at the Federico II University of Naples. The prototype was built by a shipyard which has subsequently ceased its activity, however I am currently in contact with other shipyards interested in the project.

Christening of new pilot tender "Mira" - a lightweight powerhouse
Press Release Hoek van Holland, 2 April 2020 by Next Generation Shipyards

On Thursday 2 April, Annebel de Deugd (interim manager fleet management of Nederlands Loodswezen), christened the new Dutch pilots’ tender Mira; one of the lightest tenders in the Nederlands Loodswezen fleet.

Lighter than ever
The instructions given by Nederlands Loodswezen to ship designer Camarc and shipbuilder Next Generation Shipyards had been clear: design and build a strong, waterjet driven, aluminium pilot tender that is much lighter than her predecessors. Mira weighs around 39 metric tons, whereas her predecessors weigh around 54 tons. Because of the lower weight, considerably less fuel is needed, which means the ship will emit less CO2 and soot. This makes her less harmful to the environment.

A class of its own
Mira - an M-class pilot tender - has the same hull as her L-class predecessors but is equipped with a so-called axe bow. This alone results in fuel savings of 3%. In addition, every single part of the ship’s design has been subject to careful examination to reduce weight as much as possible. Managing Director Willem Bentinck of Nederlands Loodswezen explained, "In total, Mira is about 15 tons lighter than her predecessors. This is equivalent to the weight of two adult elephants; you can imagine what a difference this weight loss makes in fuel consumption". The total fuel consumption of Mira is more than 20% lower than that of the L-class tenders, resulting in a significant reduction of CO2.



Fleet renewal
Nederlands Loodswezen’s fleet expansion is a multi-year investment programme. The fleet includes 15 waterjet driven tenders that are used for pilot embarkation/disembarkation to serve seagoing ships calling at Dutch seaports and at Flemish seaports on the River Scheldt. The new tender Mira will replace one of the Discovery class tenders now that they have reached their maximum lifespan.

Remark in times of COVID-19:
Due to the regulations concerning the Corona pandemic, the christening was held in presence of only a few people.
