All four CIP3800 HAV Ecotraders are operational

Commercially operated by HAV Shipping, these 3,800 DWT diesel-electric general cargo vessels showcase what standardized naval architecture delivers on the water: optimized hydrodynamic resistance, low fuel consumption, and high operational flexibility across short-sea and intercontinental trade lanes.

Built on our standardized CIP3800 general cargo platform, the Ecotrader fleet demonstrates how standardized cargo vessel design can accelerate fleet modernization.

Thank you to HAV Shipping for your trust in Conoship's design capabilities.

In shallow-water subsea infrastructure, standard offshore vessel designs hit a hard physical limit: draft.

To get heavy mission equipment: DP2 positioning, diving suites, heavy deck cranes, and SPS compliance onto a vessel, naval architecture could demand a large draft. But an increased draft locks shipowners out of shallow-water fields.

When Zamil Offshore needed a custom Dive Support Vessel (DSV) to operate in restricted field depths across the Gulf, standard market catalog designs were not an option, that's where Conoship stepped in.

We were brought in to execute the concept and basic design; engineering a platform that breaks this operational compromise:
↕️ 2.50m Max Draft Limit: Squeezing a 76.2m platform, 360 m² clear working deck, and dedicated LARS/ROV diving suites into an ultra-shallow profile while maintaining full ABS Class and SPS Code compliance.
🌊 CFD-Optimized Hydrodynamics: Hull lines engineered via tank testing and CFD analysis to minimize hull resistance, keeping power demand low during transit.
🍃 Operational Fuel Efficiency: Diesel-electric propulsion setup designed to reduce fuel burn and daily running costs per hour of DP station-keeping.

The result is a specialized asset built specifically to increase field accessibility without inflating daily OPEX.

🚢 ECO-8500 High Cube Series continues to grow

Recently Hansa Anholt became the second in a series of eight vessels to be delivered by Chowgule Shipyard. The 8,500 DWT multi purpose cargo vessels are designed by Conoship with a clear operation question in mind: 'How to carry more cargo with less energy, without sacrificing flexibility?'

🥇 Hans Anholt is the first in three vessels for Leonhardt & Blumberg.
🛞 All vessels will be chartered by Newtide Chartering, part of Boomsma Group.
📈 The next vessel in the series, Hansa Bornholm, has already been launched and is getting closer to delivery.

For more information about the vessels, the design process, and to watch the launch, please follow the link in the comments.

We would like to congratulate all parties involved on a successful delivery and are eagerly awaiting the delivery of the Hansa Bornholm!

Goed scheepsontwerp, een professionele uitrusting en vakkundig zeemanschap vormen de basis van veiligheid op zee. Maar als de omstandigheden extreem worden, is er één ultieme achtervang waar elke zeevarende in Nederlandse wateren op vertrouwt: de KNRM.

Om deze cruciale organisatie te steunen, slaan Conoship International en De Bock Maritiem de handen ineen. Algemeen Directeur Jan Jaap Nieuwenhuis neemt samen met Cynthia Everduin, Operationeel Directeur bij De Bock Maritiem de komende twee maanden deel aan het KNRM Captain of Sales traject, met als finale de competitie op 20 november! Tijdens die dag gaan Jan Jaap en Cynthia een dag lang strijden om het meeste geld op te halen voor de KNRM.

Als ontwerpers van maritieme oplossingen draagt Conoship graag bij aan de vrijwilligers die dag en nacht de veiligheid op het water garanderen.
Vanzelfsprekend dat De Bock Maritiem dat ook doet, veilig aan boord en veilig weer naar huis is één van de belangrijkste pijlers binnen de rederij.

Onze actiepagina is inmiddels live. We starten de teller op €0,- en willen de komende weken een serieuze bijdrage opbouwen.

Designed in 2004 and still performing in 2026

When Wallenius SOL recently acquired the ice-strengthened Ro-Ro vessels Balticborg and Bothniaborg, it marked another chapter for two ships built to withstand a tough operational environment.

Designed by Conoship International and delivered to Royal Wagenborg by Volharding Shipyards in 2004, these vessels were engineered specifically for demanding year-round service in the Baltic Sea and Gulf of Bothnia.

Key design choices that continue to drive their operational value today:
🧊 Bespoke Ice-Class Architecture: Built to Finnish-Swedish Ice Class rules, ensuring structural resilience through decades of severe winter navigation.
🚢 Optimized Cargo Efficiency: A specialized three-deck arrangement designed for seamless Sto-Ro loading of paper reels, containers, and trailers via dedicated stern and internal ramp systems.
🍃 Early Environmental Standards: Delivered with Bureau Veritas “Cleanship” and “Clean Air” notations, featuring integrated zero-dumping deck-water treatment and solvent-free coatings long before such measures became industry standard.

Great to see Balticborg continuing her runs in the Baltic!

Turkish pipeline components delivered to King's Lynn: Vessel design matters for regional port access

When moving bulk project cargo, like these large pipeline segments, getting the cargo across open water is only half the challenge. Another major test is delivering it directly to regional secondary ports with tight draft limits and tidal windows.

These shots by show the Vega Luise navigating the River Great Ouse toward King's Lynn, fully loaded on deck.

From a design perspective, handling high-volume deck loads in shallow waters requires a fine balance between:
⚖️ An optimized stability profile
🚢 Proper shallow-draft performance
🏗️ Port accessibility

The CIP3800 design is engineered to give operators like Vega Reederei the flexibility to handle different types of cargo across all sorts of European ports.

Decarbonizing European short-sea shipping isn't a one-size-fits-all challenge. It requires scalable platforms.

A recent sighting of Wilson ECO I in port offers a direct look at the first of six CIP3800 vessels designed for Wilson. At the same time, the first of eight larger CIP6300 vessels is reaching completion at Cochin Shipyard.

For fleet operators, expanding deadweight capacity on a similar design platform yields distinct operational advantages:
🔹 Optimized Hydrodynamics Across Sizes: The 6,300 DWT variant applies the low-resistance hull form established in the 3,800 DWT design, maintaining low fuel burn per ton-mile.
🔹 Standardized Engine Room Layouts: Shared electrical and mechanical systems across the 14-vessel fleet streamline crew training, maintenance protocols, and spare parts management.
🔹 Targeted Route Allocation: The 3,800 DWT vessels handle shallow-draft and restricted-access ports, while the 6,300 DWT units maximize throughput on high-density European coastal routes.

The combination of active operational data from the CIP3800 and upcoming deliveries of the CIP6300 demonstrates how standardized design platforms de-risk fleet modernization.

We recently brought our team, partners, and kids together at EM2 in Groningen for our annual summer party.

It was an evening dedicated to our community. Between great food and live music performed by our own colleagues, we took a moment to show our families what we have been building together. Seeing the kids react to the ship designs their parents work on is always a highlight.

A bit thank you to our team for bringing so much energy, and to EM2 for hosting a fantastic event 💙
