WA operator demonstrates Port Hedland commitment with locally built work boat
Dongara Marine’s growing reputation as a supplier of high-quality custom vessels for harbour service roles has been underlined with the delivery of our second work boat for operation in the world’s largest bulk port.
Jetwave Stanley Point has been operating in Port Hedland since shortly after builder Dongara Marine completed it in late April this year.
Owner Jetwave Marine Services approached Dongara Marine after learning of our first Bulldog Class work boat which was delivered to the Pilbara Ports Authority (PPA) in mid-2018.
While the PPA primarily uses its vessel for harbour maintenance activities in Port Hedland and Dampier, Jetwave Marine Services wanted a similar design but customised for work as a lines boat. It also had a preference for diesel inboard and waterjet propulsion rather than the outboards used on the PPA’s vessel.
The naval architects at Southerly Designs modified their original design to provide the expected capability and a formal proposal was made.
Jetwave Marine Services’s MD Michael Hansen said multiple factors led to the choice of the Dongara Marine offer after going to market via tender.
“We sought and received bids from a number of builders offering various designs, but ultimately determined that the Dongara Marine offer provided us with the best combination of performance, quality, and after build service,” he said.– Michael Hansen, MD, Jetwave Marine Services
With a length overall of 10 metres and beam of 3.2 metres, Jetwave Stanley Point is slightly longer and wider than the original Bulldog Class but retains the tried and tested ‘punt’ style hullform with modified forward sections. The former provides for stability, deck area, and carrying capacity while the less flat bow shape reduces resistance and improves head seas performance.
The dimensional variation reflects and enables the propulsion change, including providing for an open transom with duckboard to both protect the waterjet and enable lines to be efficiently handled over the stern.
Other features that reflect the vessel’s use for lines handling include:
Jetwave Marine Services is also using the vessel to transfer personnel within the port, and thus Jetwave Stanley Point was placed into AMSA NSCV 2D survey for up to six passengers and two crew.
Even though speed was important, Dongara Marine fabricated the vessel with scantlings that exceeds the NSCV minimum requirements.
“We know from our own experience as professional mariners that robustness and longevity are extremely valuable to operators, especially for boats like this that work in close quarters harbour situations and demanding environmental conditions,” explained Dongara Marine’s Managing Director Rohan Warr. “For that reason we almost exclusively used six millimetre aluminium plate for the structure.”
Despite the resultant weight penalty, the utility vessel has a maximum speed of 32 knots and can comfortably and cruise at 24 knots. Power comes from a single Yanmar diesel driving a HamiltonJet HJ322 waterjet.
Jetwave Marine Services’s Operations Manager, Michael Warren, said he was impressed with both the boat and Dongara Marine’s capabilities and approach.
“The quality of workmanship, and performance of the vessel are equally impressive.
“We pride ourselves on being reliable and customer-orientated, and it’s clear that Rohan and the team have a similar approach. They have been really pro-active from the outset, really listening and responding to our needs. We will be working with them again very soon.
“In fact, during the construction of Jetwave Stanley Point it became obvious to us that Dongara Marine’s capabilities and quality of service could also benefit us in other ways, and we have already contracted them for a number of significant refit and maintenance jobs on our other vessels.”– Michael Warren, Operations Manager, Jetwave Marine Services
A North West based company offering offshore and port service vessels plus quay-side support across Australia, Jetwave Marine Services has grown rapidly since being formed a little over a decade ago. It currently operates a fleet of some 20 vessels including tugs, utility vessels, barges, multi-cats and port service vessels.
Michael Hansen said the new vessel, which is named for a geographic feature in Port Hedland, was reflective of the company’s commitment to the port and its users.
“Jetwave Stanley Point is the first of four new assets making their way to our Port Hedland operations,” he said. “We are committed to expanding the depth and breadth of the services we provide there, and pleased that other Western Australian family-owned company such as Dongara Marine can be part of that.”
