Phil Akrill has laid out his long-term vision for the eastern part of the dock, including the Bullnose.
His company, Manor Property Group, bought the 500,000 sq ft site for an undisclosed fee this summer.
Under plans, the area will be transformed into a “maritime educational campus”.
Key buildings, including the derelict Lord Line trawler company office, are set to stay.
Meanwhile, the run-down area between the outer Bullnose and Mr Chu’s Chinese restaurant will be flattened.
By the end of the year the spot where trawlermen waved farewell to loved ones will be safe for people to come and reflect.
Mr Akrill’s spokeswoman Claire Levy suggested the Bullnose could host Lost Trawlermen’s Day in February.
Fishing heritage group Stand recently revealed it was likely to break with tradition in 2011 and hold the service on land near the Sailmakers’ Arms pub.
Mrs Levy said: “We fully respect Stand’s intent and ethos and wish them all the best with whatever they decide.
“The outer Bullnose area will be tidied and cleared by the end of this year. Dangerous buildings will be pulled down.
“It will be open to the public. Anyone who want to come and cast flowers into the Humber will be welcome to do so.
“It is important former trawlermen, and their loved ones, have somewhere to go to reflect.”
Speaking about longer term plans for the former dock, Mrs Levy said Mr Akrill had already compiled a team of architects and engineers.
She said: “Mr Akrill does not want commercial vulgarity. The site will not be used for more houses and apartments.
“He is tremendously supportive of the work to preserve Hull’s fishing heritage and feels this is an opportunity to give something back.
“Mr Akrill wants to create a place where people can go to remember what has been before.
“The whole development team has been appointed – ground engineers, electrical and mechanical engineers. It is all in place and running.
“We are on site now to start making it happen. We want to get this finished by 2014.”
Mr Akrill, whose company developed Queen’s Court in the city centre, is hoping to get Hull College and the city’s university, as well as other educational establishments across Yorkshire, involved in the ambitious project.
Mrs Levy said: “Using our six old buildings, we will make an offer to the educational establishments on this city and further afield.
“We will see if they are interested in creating a marine/educational facility, in a campus style, on a prime land adjacent to the Humber.
“If all the buildings are fully utilised, 3,000 people, including staff and students, could be based here.”
As well as the former Lord Line office, others set to be revamped include the former Marr and Seafish Industry Authority buildings and a listed pump house and associated buildings.
